The eyes have it in UWM’s March Science Bag show

Seeing may not be believing at this month’s Science Bag interactive lecture at the University of Wisconsin-Milwaukee (UWM).

In “Chasing the Light: Mirages, Illusions and the Human Eye,” UWM chemist Jorg Woehl will explain how we visually perceive our environment and why light can be so mysterious.

The presentation is held every Friday in March at 8 p.m. and on Sunday, March 11, at 2 p.m.

Using tools from everyday life—flashlights, mirrors, water and powdered milk (as well as lasers)—Woehl will show some of the unusual tricks light can play.

He also reveals the origins of some colors in nature, such as the redness of sunsets and the blueness of the sky.

Then see how light hides a variety of individual colors when Woehl exposes them by demonstrating the secret of colored shadows. And witness the chemistry behind light, including light that glows in the dark.

The Science Bag presentations are held in room 137 of the Physics Building, on the corner of Kenwood Boulevard and Cramer Street. The Science Bag is for the curious, ages 8 and older, and is free.
